Outcome Prediction

ABSTRACT

Outcome predictions based on historical data relating to events in a “game” (which can be a sports context, an e-sports contest, a business situation, a medical situation, or other scenarios) can be generated using a watcher process that receives event data and triggers conversion of a “different” last event received into arguments for one or more analysis protocols, which are executed against a data model created by an analysis engine. Methods, systems, articles of manufacture, and the like are described.

CROSS-REFERENCE TO RELATED APPLICATION

The current application claims priority under 35 U.S.C. §119(e) to U.S. provisional application Ser. No. 62/152,687 filed Apr. 24, 2015 and under 35 U.S.C. §120 to Patent Cooperation Treaty application serial no. PCT/U.S.2016/029089, the disclosures of which are incorporated herein by reference in its entirety.

TECHNICAL FIELD

The subject matter described herein relates to data analysis and to outcome prediction based on data analysis.

BACKGROUND

Data analysis can be a powerful tool for making predictions about possible outcomes in situations in which historical data can be effectively leveraged in light of recent events to identify outcome probabilities for one or more possible outcomes. Possible (but non-limiting) applications for a tool capable of making these outcome predictions in an efficient and accurate manner include sports outcomes, business outcomes, medical outcomes, etc. Currently available approaches to data analysis based outcome prediction are generally not accessible without significant expertise in data science and/or computer programming.

SUMMARY

In one aspect, a method can include initiating a watcher process to correspond to a designated game for which event data representative of a plurality of events occurring in the designated game are generated, converting the event data for a most recently received event of the plurality of events into one or more arguments for one or more analysis protocols, and executing the one or more analysis protocols against a data model created by an analysis engine. The watcher process receives the event data, which includes events pertaining to the designated game, from an event data source. The converting occurs when the most recently received event received by the watcher process differs from a previously received event. The executing includes the analysis engine calculating an adjusted probability of at least one outcome relevant to the designated game. The calculating reflects the event data for the most recently received event. The method can further include notifying a client application server to update a last event cache accessible by client application executing on a client machine to display an outcome prediction based on the adjusted probability.

In some variations one or more of the following features can optionally be included in any feasible combination. The analysis engine can calculate the adjusted probability using a tag overlap analysis method. The watcher process can track the plurality of events occurring during the designated game. The data source can include an external event application programming interface. The receiving of the event data can include at least one of the watcher process pulling the event data from the event data source, the watcher process receiving the event data pushed to it by the event data source, and the event data being received by the watcher process according to a preset schedule. The method can further include submitting, by a game daemon to game database, new event information comprising at least one of information about the most recently received event and analysis results comprising the adjusted probability. The designated game can include at least one of a sports contest and a baseball game.

Implementations of the current subject matter can include, but are not limited to, methods consistent with the descriptions provided herein as well as articles that comprise a tangibly embodied machine-readable medium operable to cause one or more machines (e.g., computers, etc.) to result in operations implementing one or more of the described features. Similarly, computer systems are also described that may include one or more programmable processors and one or more memories coupled to the one or more processors. A memory, which can include a non-transitory computer-readable or machine-readable storage medium, may include, encode, store, or the like one or more programs that cause one or more processors to perform one or more of the operations described herein. Computer implemented methods consistent with one or more implementations of the current subject matter can be implemented by one or more data processors residing in a single computing system or in multiple computing systems. Such multiple computing systems can be connected and can exchange data and/or commands or other instructions or the like via one or more connections, including but not limited to a connection over a communication network (e.g. the Internet, a wireless wide area network, a local area network, a wide area network, a wired network, or the like), via a direct connection between one or more of the multiple computing systems, over a shared bus, etc.

The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims. While certain features of the currently disclosed subject matter are described for illustrative purposes in relation to outcome prediction in a sports context, it should be readily understood that such features are not intended to be limiting. For example, outcome predictions consistent with the approaches described herein can be applicable to many situations in which historical data are available. Such situations can include physical sports, electronic sports (e.g. video games), gambling on physical and/or electronic sports, medical treatments and/or health outcomes, investment decisions, business outcomes, etc., among others. The claims that follow this disclosure are intended to define the scope of the protected subject matter.

DETAILED DESCRIPTION

Currently available approaches to data analysis and predictive modeling generally lack a capability to process potentially large historical data sets in a manner that allows outcome predictions to be generated and presented to a user quickly (even for very large historical data sets) and without the user needing a detailed knowledge or expertise in data analysis techniques, programming, etc. Various features described herein may provide advantages over previously available approaches. Such advantages may include, but are not necessarily limited to, improvements in usability (e.g. user experience), greater efficiency in use of computing resources (e.g. bandwidth, memory, processor cycles, etc.), and the like.

FIG. 1 shows a multi-layer architecture diagram of a prediction system 100 consistent with implementations of the current subject matter. The prediction system 100 includes a backend layer 102, an application layer 104, and a client layer 106. The backend layer 102 receives data inputs 110, which can include one or more historical data sources 112 and an event data source 114, which can, in some examples, be an event application program interface (API). In an example related to outcome predictions for a baseball game, a historical data source 112 is a baseball related historical data source, and an event data source 114 is a baseball event API. The backend layer 102 also includes an analysis engine 120, which accesses the historical data source 112 to make a series of calculations based on a data model, as well as a prediction handler daemon 122. It will be understood that the backend layer 102, the application layer 104, and the client layer 106 can optionally be implemented all on a single computing system or alternatively with one or more components implemented on different computing systems. In an example in which implementation occurs on multiple computing systems, discrete systems or groups of systems can be assigned to functions of the various layers. Alternatively, the components of the layers 102, 104, 106 need not be segregated in this manner (e.g. two or more systems can include components of the backend layer 102 and the application layer 104, etc.).

In an example consistent with FIG. 1, in which the prediction system 100 is used for sports-related predictions, and more specifically for baseball-related predictions, the prediction handler daemon 122 is a game daemon 122. Every night during a baseball season (or at some other relevant interval), the game daemon 122 pulls or otherwise accesses a schedule of upcoming games (e.g. games scheduled for the next day) and launches a watcher process 124 for each upcoming game. The launching can involve starting up (initiating, instantiating, etc.) a thread or other computational process on one or more computer systems and/or one or more programmable processors. Each watcher process 124 advantageously starts up before its game is scheduled to begin. Once it is started, the watcher process 124 pulls event data about its watched game from the event data source 114 at some relevant interval. The analysis engine 120 and the prediction daemon can exchange analysis protocols 126 and analysis results 130 as discussed in more detail below.

In the application layer 104, a client application server 140 includes a last event cache 142. The client application server 140 can be in communication with a user database 144, which can include a user table 146 and a user attribute table 150, and also with a game database 152, which can include an analysis table 154, a play-by-play (PBP) table 156, and a game table 160 as discussed in more detail below.

The client layer 106 can include authentication functionality 170 as well as a component or components for requesting information about current or upcoming games (today's games request 172), a last event 174, and a last prediction 176 from the client application server 140 as discussed in more detail below. In some examples, the client layer 106 can be part of or otherwise associated with a television or other video broadcast of a sporting event such as a baseball game. For example, the predictions discussed herein can be shown via one or more graphical overlays upon or windows embedded within a video stream showing a baseball game or other sporting event.

FIG. 2 shows a process flow chart 200 illustrating features of a method consistent with implementations of the current subject matter. At 205, a watcher process 124 is launched (e.g. initiated, instantiated, etc.) to correspond to a designated game. The watcher process 124 performs tasks relating to tracking events occurring in the game for which the watcher process 124 is launched.

During the game (which as noted elsewhere herein, can broadly refer to some collection of events for which relevant historical data are available and for which outcome predictions are desired), at 210, the game watcher process receives event data pertaining to the designated game from an event data source. The event data source in some examples can be an external event API 114, and the receiving of event data can occur as part of a pull operation (e.g. pulling the event data from event data source driven by periodic requests from the watcher process 124), a push operation (e.g. the watcher process receiving the event data pushed to it by the event data source), according to a preset schedule, or the like. The watcher process 124 can advantageously pull event data from the event data source 114 on regularly or irregularly spaced time periods, which can have a duration that is relevant to the parameters of the designated game (e.g. every 5 seconds, etc.). A relevant duration can be defined as a period having a sufficiently short duration to ensure capture of a newly generated quantum of event data prior to a next event in the designated game for which a prediction can be generated but also of sufficiently long duration to avoid multiple calls to the event data source 114 for which no new event data has been generated.

In the illustrative example of a baseball game, the period can be on the order of one to a few seconds such that event data regarding a most recent pitch and any other relevant game events (e.g. a change in locations or numbers of base runners due to a stolen base or a caught stealing or pickoff, etc.) can be received in time to be reflected in a prediction for a next pitch. In some examples, a push operation can be advantageous for supplying event data to a watcher process 114, assuming that the event data source 114 is configured appropriately. In an example in which the event data source 114 is a third party (e.g. external) application programming interface (API), a data query engine can be used as an intermediary such that the data query engine accesses the third party API via a pull operation with some set frequency (e.g. every second) and in turn pushes relevant data to each of one or more concurrently running watcher processes 124. Alternatively, a call for new event from the watcher process 124, a push of new event data from the event data source 114, and/or a scheduling of a later delivery of event data can be triggered or otherwise determined by previously received event data. For example, in a baseball context, receipt by the watcher process 124 of event data indicating a last out of an inning can cause the watcher process to delay a next call for a pull of event data for an expected time period before a next inning begins (e.g. 2 minutes, etc.).

At 215, when a most recently received event received by the watcher process 124 differs from a previously received event (e.g. because an additional, new event has occurred during the designated game), the watcher process 124 converts the most recently event received into one or more arguments for one or more analysis protocols 126 (e.g. baseball analysis protocols, soccer analysis protocols, etc.) and then runs the analysis protocols 126 against the analysis engine 120. The analysis engine 120 converts each analysis protocol 126 into one or more algorithms, which it runs against the historical data received from the historical data source 112 to generate analysis results 130, which are returned to the prediction daemon 122.

At 220, the one or more analysis protocols are executed against a data model created by the analysis engine 120. The analysis engine 120 calculates adjusted probabilities of outcomes given the situational variables of the current game state. In a example in which the designated game is a baseball game, outcomes for which adjusted probabilities can be calculated can include one or more of pitch outcomes, at-bat outcomes, scoring outcomes, game result outcomes, etc. In another example in which the designated game is soccer, outcomes for which adjusted probabilities can be calculated can include one or more of which player will score next, likelihood of a penalty kick being successful, a probability of a goal being scored within a certain amount of time, which team is likely to score next, etc. In yet another example in which the designated game is American football, the outcomes for which adjusted probabilities can be calculated can include one or more of which player will score next, whether a field goal will be made or missed, which team will score next, whether a next play will be a running play or a passing play, whether a penalty will be called on the next play, etc.

In some examples, an analysis engine 120 can include a statistics engine, which can optionally be implemented via a cloud-based service, or on dedicated machines. The analysis engine 120 can be based on one or more programming models, such as for example MapReduce or the like, and can be capable of calculating analysis statistics in parallel. Additionally, the analysis engine 120 can include modules for different variable types. The analysis engine can also calculate enrichment statistics and can perform one or more statistical tests, for example, using a tag overlap analysis method. Tag overlap can be characterized as a situation in which tagged values overlap with the members of a data set n more than would be expected by random chance. For numeric variables, this inquiry can involve determining whether the data distributions are significantly different, for example using a T-test, or one or more non-parametric tests. In some implementations of the current subject matter, the analysis engine 120 can implement one or more machine learning methods.

The analysis engine 120 is configured based on data from the historical data source 112. In the example of a baseball game event prediction, the historical data source 112, which includes multivariate data relevant to the predictions being made. The analysis engine 120 converts the one or more analysis protocols 126, runs the algorithm, and returns the analysis results 130 to the prediction daemon 122. In this manner, the historical database is converted to a smaller footprint via various compression techniques.

The historical data source 112 can generally include data from one or more databases or other sources that is relevant to outcome predictions for the type of game being analyzed. For example, for a baseball prediction implementation, the historical data source 112 can include one or more databases storing baseball historical data, such as for example player and action outcomes for batters and pitchers with relevant situational information (e.g., the count, number of baserunners and/or outs, current score, inning, other game situation data, specific batter vs. specific hitter outcomes, umpire characteristics, weather, ballpark characteristics, etc.). In a soccer example, the historical data source 112 can include one or more databases storing soccer historical data, such as for example player and action outcomes for players at different positions with relevant situational information (e.g., remaining game time, weather conditions, type of defense being played, outcomes against similar opposing teams or players, outcomes against a given goalie or goalies with similar styles or other characteristics, referee characteristics, current score, etc.). In a non-sports example (e.g. medical outcomes), the historical data source 112 can include one or more databases storing relevant historical data, such as for example patient and treatment variable outcomes for patients, caregivers, treatment approaches, etc. with relevant situational information (e.g., illness state at the start of a treatment, patient age and general health assessment, other treatments or pharmaceuticals recently experienced by the patient, experience level of the caregiver, type of medical setting, etc.).

At 225, when the prediction daemon 122 has new event information and/or analysis results 130 about a game, the prediction daemon 122 submits that information to the appropriate tables in the game database 152 and sends a notification to the client application server 142 to update its last event cache 142 containing latest game and event information.

A user can begin using the prediction system 100 by logging in, or on a first use, by registering for a login identity. These operations can be completed via an authentication module 170 or other similar functionality executing on a client machine, which can be any kind of computing device (e.g. a personal or laptop computer, a mobile device such as a phone or tablet, etc.). FIG. 3 shows a screenshot 300 illustrating an example of a login screen. Logging in can occur via one or more of a Web interface (e.g. accessed via a Web browser executing on a computing device), a dedicated application (e.g. a standalone program separate from a browser such as an “app” running on a computing device), an applet (e.g. a program executed within a browser, such as a Javascript applet), etc. The client application server 140 processes the login request, and authenticates the user for access to the features of the prediction system 100. The client application server 140 can then update the login/registration information in the user database 144.

When a user is logged in, a game panel can be displayed to the user via a display device on the client machine at 230. The screenshot 400 of FIG. 4 shows an example of a game panel, which can show a listing or other visual representation of the games that are being played currently or that are scheduled to be played that day, as well as information about those games (e.g. whether or not a game has started, is in progress, or has already ended, the scheduled start time for a game, the team logos, the venue, the records of the teams playing in the game, etc.). For a game that is in progress or already ended, the game panel can display typical box score information, such as for example an in-progress or final score, key individual or team statistics, etc. As noted above, the client layer can supply display data regarding a predicted situational batting average or other relevant outcome predictions relating to a game such that these measures are displayed in conjunction with a video stream showing the game and are dynamically updated according to changes in current game state as reflected by event data about the designated game.

Upon receipt by the client machine of a user choice of a game from the game panel, a pitch prediction panel is displayed at 235. The user's game choice can be recorded in a user attributes table 150 in the user database 144, which can optionally be stored at the application layer 104. FIG. 5 and FIG. 6 show screenshots 600, 700 illustrating an example of a pitch prediction panel consistent with implementations of the current subject matter. In the baseball-related example illustrated in the screenshots of FIG. 3 through FIG. 6, the pitch prediction panel can display the latest information for a single game, such as for example the current state of the game (e.g. one or more of the team that is currently at bat, the inning, the number of outs, the number of runners on base, the pitcher name and whether the pitcher throws right or left handed, the batter name and whether the batter bats right or left handed, the count of balls and strikes, a player image such as a thumbnail picture of the pitcher and/or batter, etc.), as well as the predictions made by the analysis engine 120 about the probability of what will happen next. FIG. 5 shows the pitch prediction panel for a first game situation with a 2 ball, 2 strike count and 2 outs in the bottom of the 8^(th) inning, and FIG. 6 shows the pitch prediction panel for a second game situation a pitch later, with the count now 3 balls and 2 strikes. The batter's predicted situational batting average for the current situation is updated from 0.355 in FIGS. 5 to 0.225 in FIG. 6 to reflect predictions by the analysis engine 120.

In some implementations of the current subject matter, requests for predictions can be limited to coming from authenticated users of the prediction system 100. After competing the authentication process, the client layer 106 can receive an authentication key. The client layer 106 can use the authentication key to query the client application server 140. Queries can include getting information about all games today, the last event for a given game, and the last prediction made by the system for a given game.

The examples presented herein are discussed in relation to an implementation for providing outcome predictions in association with the sport of baseball. It will be readily understood that similar approaches can be applied both to other sports and as to other situations unrelated to sports in which data-driven predictions have value. For example, use of the term “game” should be interpreted to refer to any kind of sporting event (e.g. a match, a contest, a meet, a competition, etc. Additionally, in a non-sports example, “game” can refer to an event or set of events during or for which data-driven predictions are made.

In some implementations of the current subject matter, outcome predictions generated using one or more of the features described herein can be used for generating odds for gambling transactions relating to “proposition bets” that may be made during the course of a game. For example, a prediction that a most likely next player to score a goal in a soccer match can include a probability of this outcome. Odds for a proposition wager regarding which player will score next can offer a payout of somewhat less than this statistical probability such that the “house” (e.g. the wagering establishment) receives a profit on each wager. For example, if the probability of player X being the next to score a goal is calculated using the above-noted techniques to be 20%, a wager can be offered in which a gambler makes a wager for $1 which, if successful, would pay the gambler back $4 (a 4 to 1 payoff rather than the 5 to 1 payoff that would be indicated by the 20% probability).

Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.

A computer-implemented method comprising: initiating a watcher process to correspond to a designated game for which event data representative of a plurality of events occurring in the designated game are generated, the watcher process receiving, from an event data source, the event data, which comprise events pertaining to the designated game; converting the event data for a most recently received event of the plurality of events into one or more arguments for one or more analysis protocols, the converting occurring when the most recently received event received by the watcher process differs from a previously received event; executing the one or more analysis protocols against a data model created by an analysis engine, the executing comprising the analysis engine calculating an adjusted probability of at least one outcome relevant to the designated game, the calculating reflecting the event data for the most recently received event; notifying a client application server to update a last event cache accessible by client application executing on a client machine to display an outcome prediction based on the adjusted probability.
 17. A computer-implemented method as in claim 16, wherein the analysis engine calculates the adjusted probability using a tag overlap analysis method.
 18. A computer-implemented method as in claim 16, wherein the watcher process tracks the plurality of events occurring during the designated game.
 19. A computer-implemented method as in claim 16, wherein the data source comprises an external event application programming interface.
 20. A computer-implemented method as in claim 16, further comprising submitting, by a game daemon to game database, new event information comprising at least one of information about the most recently received event and analysis results comprising the adjusted probability.
